reducing exhaust drone

Hooker Max Flo is what I have, no drone. lol
I used the Aero Chamber before the switch, a good sounding non-restrictive muffler.
I ran the hooker aeros on my car, 3 1/2 in/out. I really liked the tone, ran nines thru them. The hooker max flows won the engine masters 1000hp muffler shootout handily.
